Party Foul Adam Raby Christine Waite Philip Huber Travis Owens
Design • Platform • Ramp • Mousetrap • Pendulum • Cup on Pivot
The Intelligent Side of Party Foul • Conservation of Linear Momentum (Car and ball) • mcarvcar+mballvb all= mcarvcar’+mballvball’ • Conservation of Angular Momentum (Pendulum and cup) • Ipen.ωpen. + Icupωcup = Ipenωpen’ +Icupωcup’ • Gravitational Potential Energy to Kinetic Energy(Ball rolling down ramp ; ball falling from cup) • mgh=½mv2 • Vfinal=√2gh/1+x ; vfinal=√2gh • vfinal=√[2(9.81m/s2)(.11m)]/[3/2] ; vfinal=√2(9.81m/s2)(.34cm) • Vfinal=1.2m/s ; vfinal= 2.58m/s • Torque (Ball striking cup to flip it over) • τ=Iα and τ=rx F
Road Bumps • The Mousetrap: can kill a mouse but cannot cut thread. • The wood: either splits or the nails aren’t long enough. • Stability: “just make the base bigger.” • The solution for any problem: Duct tape.
Good Riddance, Party Foul. • What started as a “simple idea” turned out to be not so simple. • Worked out all of the problems to the point of functionality. • Completed the goal and worked well together.
